12th notes (1.5x faster than 8th notes) are represented by purple arrows. These types of notes are commonly used in polyrhythms and are used to create 12 beats instead of 8 in one measure (4/4 time signature).

32nd notes (2x faster than 16th notes) are represented by red-orange arrows. These aren't very common and can make for some very nasty patterns in the game. They're the .s in 1.e.&.a.2.e.&.a.3.e.&.a.4.e.&.a.

48th notes (2x faster than 24th notes) are represented by turquoise arrows. The main application of these are being grace notes. If not used as a grace note, 48th notes can be very fast (48 beats per measure in 4/4 time signature).

64th notes (2x faster than 32nd notes) are represented by green arrows. These are mainly used as grace notes as well, but if not used as a grace note, 64th notes can be brutally fast. They're the 's in 1'.'e'.'&'.'a'.'2'.'e'.'&'.'a'.'3'.'e'.'&'.'a'.'4' .'e'.'&'.'a'.'.

192nd notes (4x faster than 48th notes) are represented by white arrows. The primary purpose of 192nd notes are for voice-stepping and grace notes. Some step artists use 192nd notes as a technique to make their stepfile look more colorful (e.g. Counting Snow), but for the most part they're the same thing as the note they're the closest to.
